Part 2. MARKING CONDITIONS – REFERENCING THE

NF MARK

This Technical Document specifies the conditions of marking and referencing the NF Mark provided in the

certification reference system of the NF Mark - Rigid Non-Plasticised PVC Pipes and Fittings.

2.1 REPRODUCING THE NF LOGO ON THE CERTIFIED PRODUCT

2.1.1 General

The NF logo shall ensure the identification of each certified product.

The trade reference of the certified product must be reserved for the NF mark.

The manufacturer must not use the NF mark except to single out certified products without there being any risk of

confusion whatsoever.

The logo’s graphic tools are available from the CSTB Technical Department (Tel.: +33 (0)1 64 68 89 52 – E-mail:

[email protected]).

It is recommended that the holder remit to CSTB, in advance, all the documents upon which the NF mark appears.

The NF logo, constituting certification identification by a third party with regards to the reference standards cited

on page 2 of this Technical Document, must be affixed in accordance with the conditions defined in those

standards.

The black and white version of the NF logo can be used.

2.1.2 Marking pipes and fittings

2.1.2.1 Marking pipes

Marking of pipes must be carried out in a way that is visible and indelible and which can be read by the naked eye,

on a generatrix and contain, every meter or less, the following set of information:

- the trademark or symbol filed by the manufacturer with the mandated bodies.

- the manufacturer’s identification number assigned upon notification of admission and possibly the

production site designated upon notification of admission (if there are multiple factories).

- the monogram

or

and the symbol of the family (E for siphonic system

discharge pipes)

E or E

Holders have the option to use:

- Either the new logo followed by the letter E, as follows: E

- Or, as an exception, when using the logo creates technical and/or material difficulties, the old logo

mailto:[email protected]



The new certified products shall comply with the NF graphic charter in force.

Note: a negative version of the logo can be used.

- the material identification symbol: PVC

- the pipe dimensions:

• for the siphonic systems Discharge family:

nominal external diameter x nominal thickness (or minimum) and the name "SIPHONIC".

- mark for production identification: date (dd/mm/yy) or day number and year of manufacture (xxx/yy)

(or batch no. indicating the manufacturing date: in this case, the definition of this number must be sent to

the mandated body).

Note: the choice of marking method is left to the manufacturer. Any other additional marking is permitted on the

condition that the sequence of NF information is not broken and it causes no confusion during use; in this case, the

sequence of NF information must be framed by three lines of approximately 3 cm.

Unless specifically authorised by the mandated body after consultation with the Application Committee, double-

marking products is prohibited when marking relates to an application that is not covered by the mark.

Examples:

2.1.2.2 Marking fittings

b.1. Mandatory information on fittings

For fittings with diameters 50 mm

Each fitting must bear the following information, marked indelibly:

- trademark or symbol filed by the manufacturer with the mandated bodies.

- nominal dimensions (in the case of a single fitting or a reducing fitting; in the latter case, the order

indicated for the designation must be followed).

- values of connection angles.

Example:

If multiple trademarks are filed with the mandated bodies, the identification number of the manufacturer, assigned

upon notification of admission, must be mentioned in addition to the above information.

For fittings with diameters > 50 mm

Each fitting must bear the following information, marked indelibly:

- trademark or symbol filed by the manufacturer with the mandated bodies.

- nominal dimensions (in the case of a single fitting or a reducing fitting; in the latter case, the order

indicated for the designation must be followed).

- values of connection angles.

- NF monogram and family symbol arranged as shown below, notwithstanding the NF mark’s graphic

charter.

Holders have the option to use:

- Either the new logo followed by the letter E, as follows: E

- Or, as an exception, when using the logo creates technical and/or material difficulties, the following

monogram:


E


In cases of FF sleeve couplings or if moulding conditions do not allow marking of the NF monogram described

above, this is optional, unless using the monogram E is possible.

Example:

If multiple trademarks are filed with the mandated bodies, the identification number of the manufacturer, assigned

upon notification of admission, must be mentioned in addition to the above information.

Note: the location of the marking and the methods used are left to the manufacturer. Any other additional marking

is permitted on the condition that its location is separate from the NF marking and it causes no confusion during

use.

b.2. Additional recommended information on fittings (optional)

Each fitting may bear the following information:

- the symbol identifying the material (PVC),

A campaign corresponds to the period between the start of manufacturing of a product reference number and the

switch to the next number.

3.2 QUALITY MANAGEMENT OPTION

The implemented quality assurance plan must enable product compliance with the specifications of the standards

and of this regulation.

Consequently, the manufacturer must complete or ensure completion of the specified tests per the frequencies

defined in the quality assurance plan, certain tests being able to be considered "type" tests (for putting new

equipment in place or using a new formulation, for example).

The dimensional quality control testing carried out on the same fittings from TD2 of this reference system are

deemed to satisfy the dimensional verifications of this reference system.

(**) Case of manufacturers holding the NF Mark TD2: the range admitted in TD6 being geometrically identical to the range

admitted in TD2, inspection of dimensions will not be performed. Only the TD6 range not matching TD2 will be inspected;

this TD6 range is distinguished by angles and Z- and H-lengths different from those of TD2. A list of this range shall be

made available in the factories during an audit by the certification body.
